Unpacking the X3B
Remove the following items from the carton:
1.
X3B Horn/Light Tower with mounting plate. Note: If the X3B was ordered
for the BD-22 electrode, the carton should contain the BD-22 mounting
plate (part #91243).
2.
Power Cord (part #03780)
3.
A 4 conductor cable, with a 9-pin terminal block connector on one end and
a 10-pin connector on the other. (part #91247)
Connecting the X3B
1.
Decide which side of the spark tester you wish to mount the X3B. Note that
you may have to remove the small plate from the X3B chassis and secure it
to the opposite side so that the green X3B terminal block is accessible from
the spark tester back panel. Mount the X3B using the mounting plate and
the (4) bolts that attach the end guard to the spark tester, as shown in the
picture to the left.
2.
Make sure the spark tester is off before wiring to the X3B.
3.
Locate the 10-pin green terminal block on the back of the X3B and the 9-
pin terminal block on the back of the spark tester. The X3B is supplied with
a 4 conductor cable. The 10-pin connector will plug into the X3B terminal
block and the 9-pin connector will connect to the spark tester terminal
block. Prior to inserting them, pins 1-5 of the 10-pin connector should be
wired to accessory equipment with 22 gauge or larger, stripped ba
ck 1/4”
(6mm) and fed into the green terminal block connector at the proper pin
numbers, as described on the following page. Pins 1-3 of the 9-pin
connector should be wired as described on the following page.
4.
When wiring the two units, notice that pins 5-8 on the spark tester are now
being used to communicate with the X3B. The functions of pins 5-8 on the
spark tester have now been transferred to pins 1-5 on the X3B terminal
block. When the wiring is complete, plug in the power cords to both X3B
and the spark tester.
